“…For instance, research has shown that interactions based on egalitarian dialogue operating in small heterogeneous groups of students known as interactive groups (IGs) boost children's learning of mathematics, particularly in terms of mathematics understanding and problem-solving, contributing to the improvement in mathematics performance (Díez-Palomar and Olivé, 2015;Flecha, 2015;García-Carrión and Díez-Palomar, 2015). The evidence shows that the advancements in mathematics skills due to participating in IG also foster an increase in students' self-confidence, self-efficacy, and a positive attitude toward mathematics (Díez-Palomar and Olivé, 2015; García-Carrión and Díez-Palomar, 2015;Díez-Palomar et al, 2018). In a similar vein, an experimental study conducted to analyze children's productivity when working in groups to solve math problems showed that the children in the target group engaged in collaborative, enthusiastic, and productive ways more than the control group and, as a result, achieved greater improvements in their attainments in mathematics (Mercer and Sams, 2006).…”
